Experts say devastating hurricane so early in season is ‘big wake-up call’ – and predict even more powerful storms

The poignancy was unmistakable: prognosticators at Colorado State University amended their already miserable seasonal tropical cyclone forecast on Monday precisely as Hurricane Beryl was filling Houston’s streets with floodwater and knocking out power to more than 2m homes and businesses.

“A likely harbinger of a hyperactive season” was how CSU researchers characterized Beryl, which set numerous records on the way to its Texas landfall, including the earliest category 5 hurricane, strongest ever June storm, and most powerful to strike the southern Windward Islands.

Campaigners welcome ‘seismic shift’ and urge museum bosses to review links with other fossil fuel sponsors

The Science Museum has been forced to cut ties with oil giant Equinor over its sponsor’s environmental record, the Observer can reveal.

Equinor has sponsored the museum’s interactive “WonderLab” since 2016, but the relationship is now coming to close, a move that will be seen as a major victory for climate change campaigners.

This isn’t down to one wet, cold British spring but a disturbing longer-term decline in insects. Thankfully, we can help

Anyone with even a passing interest in the natural world will have noticed a dramatic phenomenon this year: a lack of insects. Perhaps most noticeable is the near-absence of butterflies. Species that are usually common, such as large and small whites, small tortoiseshells, gatekeepers, ringlets, peacocks and meadow browns, are in many places down to the point of having almost disappeared. This is certainly the case where I live, in Cambridge.

Bee populations seem to be down here, too, with flowery margins that would at this time of year normally be alive with pollinators now eerily quiet. Hoverflies are depleted, moths scarce and aphids have either appeared very late or not at all. Buddleia bushes, with their fragrant mauve flowers that are usually festooned with butterflies, moths and many other insects, sit naked of their normal visitors.

Scientists fear adaptations to global heating may leave some species struggling to mate successfully

An ambush bug with a darker-coloured body is better at snagging a sexual partner than its brighter counterpart when it is chilly. Darker males can warm up more easily in the early mornings, and therefore get busy while everybody else is still warming up.

This is one of the many examples of how temperature affects colouring in insects, and in turn can affect their ability to mate, according to a new review article published in the journal Ecology and Evolution.

He was keen to impress in his new job just as a heatwave was gripping the country. What can David Azevedo’s story tell us about the threat increasingly extreme weather poses to human health?

For Anne-Marie Azevedo, 13 July 2022 started off like a normal day. Her brother David was staying with her while he got his life back on track after a period of unemployment. He was on the third day of a new job in construction and had been asked to work extra hours. Eager to make a good impression, David was up and out of the door first thing.

As she got ready for work later in the morning, Anne‑Marie thought David had mistakenly picked up her house keys, so she called him. She was reassured to hear that he sounded fine, despite the fact that the previous evening he had been exhausted and visibly unwell from the heat. France was in the grip of an intense heatwave, and he was working outside all day. David hadn’t taken the keys, so after a quick chat Anne-Marie got on with her day.
